SmartZone-4TM a Zone Control System for the 21st Century
A zoning system is made up of a controller that receives information from Zone Thermostats in multiple locations. The controller then gives commands to HVAC equipment and specific Motorized Zone Dampers in order to control temperature in each of the thermostat locations.
XCI Network Thermostats and Zoning are cost effective solutions to poor room-by-room temperature control and expensive utility usage. XCI Controls distributes computer-controlled thermostats that have proven to be popular alternatives to over-priced building automation systems in the light commercial market. XCI Electronics engineers, having years of experience in HVAC controls engineering, recognized a need to design and produce superior, cost effective zoning systems.
Yesterday’s Technology is Being Replaced by New Ideas
It used to be that zone control was as crude as turning off individual radiators or installing window air conditioners for each room. Those methods were costly, unsightly, and largely impractical. Modern buildings require modern zone control systems that will work invisibly to provide clean, healthy, and comfortable heating and cooling exactly where the customer wishes. New technologies and ideas available today enable zone control systems to offer more features and better comfort than ever before.
Supply Air Temperature Adjustments
When only a few zones are open, excess conditioned air called bypassed air should be re-circulated into the return plenum instead of being routed to a dump zone. It is inefficient and often ineffective for an HVAC system to dump as much as 70 per cent of cold or warm air into another part of the building – the practice when using a dump zone. For maximum efficiency the air should be re-circulated through the system. Using this re-circulated bypassed air as entering air can cause extreme supply air plenum temperatures if the bypassed air is not monitored and accurately controlled.
XCI Controls work with push button adjustable set points in one degree increments. This type of sensor monitors and delivers accurate supply air temperature regardless of relative humidity.
An added benefit of electronic limit control is intelligent second stage operation. It allows for staging based on supply air temperature rather than using a simple timer to activate the second stage.
Ease of use in achieving absolute comfort
The one who ultimately benefits from these leading edge advantages is you. With a modern zone control system, all you do is set the thermostats. Everything else is invisible and automatic. The only one who needs to look at the control panel is the technician.
Companion products to the newest zone control systems offer even more advantages, such as the ability to set all thermostats from a personal computer. By incorporating network thermostats into the zone control system, you gain complete flexibility through a Windows® based program. Monitor and make changes from a remote location.
Today’s zoning systems have reached a level of technology that includes electronic limit control for supply air, a second stage that activates when demand dictates, ease of installation, ease of operation, and comprehensive diagnostics. Put together, these new ideas offer numerous benefits for achieving absolute comfort in your home or business.
